                <h1>
                    Using filters
                </h1>
<!-- END PAGE TITLE -->
                <div><p>You can use filters to clean up or retouch your photos,
apply special art effects that give your image the appearance of
a sketch or impressionistic painting, or create unique transformations
using distortions and lighting effects. The filters provided by
Adobe appear in the Filter menu. Some filters provided by third-party
developers are available as plug‑ins. Once installed, these plug‑in
filters appear at the bottom of the Filter menu. </p>
<p>Smart Filters, applied to Smart Objects, let you use filters
nondestructively. Smart Filters are stored as layer effects in the
Layers panel and can be readjusted at any time, working from the
original image data contained in the Smart Object. For more information
on Smart Filter Effects and nondestructive editing, see <a href="WSB3154840-1191-47b7-BA5B-2BD8371C31D8a.html">Nondestructive editing</a>.</p>
<p>To use a filter, choose the appropriate submenu command from
the Filter menu. These guidelines can help you in choosing filters:</p>
<ul><li><p>Filters are applied to the active, visible layer or a
selection.</p>
</li>
<li><p>For 8‑bits-per-channel images, most filters can be applied
cumulatively through the Filter Gallery. All filters can be applied
individually.</p>
</li>
<li><p>Filters cannot be applied to Bitmap-mode or indexed-color
images.</p>
</li>
<li><p>Some filters work only on RGB images.</p>
</li>
<li><p>All filters can be applied to 8‑bit
images. </p>
</li>
<li><p>The following filters can be applied to 16‑bit images: Liquify,
Vanishing Point, Average Blur, Blur, Blur More, Box Blur, Gaussian&#160;Blur,
Lens&#160;Blur, Motion&#160;Blur, Radial Blur, Surface Blur,
Shape Blur, Lens Correction, Add Noise, Despeckle, Dust&#160;&amp;&#160;Scratches,
Median, Reduce Noise, Fibers, Clouds, Difference Clouds, Lens Flare,
Sharpen, Sharpen Edges, Sharpen More, Smart Sharpen, Unsharp Mask,
Emboss, Find Edges, Solarize, De-Interlace, NTSC Colors, Custom,
High Pass, Maximum, Minimum, and Offset.</p>
</li>
<li><p>The following filters can be applied to 32‑bit images: Average
Blur, Box Blur, Gaussian Blur, Motion Blur, Radial Blur, Shape Blur,
Surface Blur, Add Noise, Clouds, Lens Flare, Smart Sharpen, Unsharp
Mask, De-Interlace, NTSC Colors, Emboss, High Pass, Maximum, Minimum,
and Offset.</p>
</li>
<li><p>Some filters are processed entirely in RAM. If you don’t
have enough available RAM to process a filter effect, you may get
an error message.</p>
</li>
